Question 46
BTNAT2 marksNeeds review
A microbial strain is cultured in a 100 L stirred fermenter for secondary metabolite production. If the specific rate of oxygen uptake is 0.4 h⁻¹ and the oxygen solubility in the broth is 8 mg/L, then the volumetric mass transfer coefficient (
) (in s⁻¹) of oxygen required to achieve a maximum cell concentration of 12 g/L is (up to two decimal places)
